SummaryThe clinical impression that spinal cord injured and traumatic lower limb amputees are more prone to develop degenerative diseases was investigated by comparing the prevalance of hypertension, ischaemic heart disease, and diabetes mellitus in these two patient groups with the prevalence of these diseases among a group of healthy age matched controls. Seventy seven spinal cord injured patients and 53 amputees ful filled the criteria for inclusion in this study. Our results show a significant increased incidence of hypertension and ischaemic heart disease among those with spinal cord injuries compared with their controls; and among the amputees, a significant in creased incidence of ischaemic heart disease and of diabetes mellitus.
The effects of objective and subjective overload, and of physical and emotional burnout, on cholesterol and triglycerides levels were studied in a quasiprospective design. The possible moderating effects of emotional reactivity on these relationships were also investigated. The study's hypotheses were tested separately for male and female employees. Time 1 (T1) data were collected from 665 healthy employees (30% women) while they were undergoing periodic health examinations in a health-screening center. Time 2 (T2) measures of cholesterol and triglycerides were collected 2 to 3 years after T1. The hypotheses were tested by regressing each T2 criterion on its T1 level; the control variables of age, obesity, diet, alcohol consumption, and smoking; and the other predictors. For female employees, the T2-T1 changes in the serum lipids were positively predicted by emotional burnout, as expected, but negatively predicted by physical fatigue. For male employees, both types of T1 burnout were positive predictors of the T2-T1 change in total cholesterol.
SUMMARYScarce data are available on epidemiology of varicocoele, the most common surgically correctable cause of male infertility. The objectives of this study were to evaluate the association between body mass index (BMI) and varicocoele and to assess trends in prevalence over time. We conducted a nationwide population-based long-term (1967-2010) study among 1 323 061 Israeli adolescent males using data from mandatory medical examination. BMI was grouped into underweight, normal weight, overweight and obese categories by percentiles adjusted for age in months and by further classification to five categories within normal weight. Univariable and multivariable logistic regression models were constructed, adjusting for possible confounders. Varicocoele prevalence (N = 47 398) increased during the study period from 1.6% for the 1950-1954 birth cohort to 4.6% for the 1990-1993 birth cohort, with the steepest rise in the normal weight group. Varicocoele unadjusted rates were highest (4.1%) among underweight and lowest (1.6%) among obese. In a multivariable model, adjusted for birth cohort, height, age and socio-demographic factors, we found a decreased risk for varicocoele in the overweight group [odds ratio (OR) = 0.51, 95% confidence interval (CI): 0.49, 0.54] and the obese group (OR = 0.34, 95% CI: 0.32, 0.37), compared with the normal weight group. Within the normal weight group, a monotonic inverse association between BMI percentile and varicocoele was observed, most notable among 75-84.9 percentile compared to 25-49.9 percentile (OR = 0.65, 95% CI: 0.63, 0.68). In conclusion, varicocoele is common among adolescents in Israel, and its prevalence had increased in recent decades, providing clues to direct further andrological research on the role of modern lifestyle and environment in the aetiology of varicocoele. BMI, across percentiles, was found to be monotonically inversely associated with varicocoele, thus directing research and clinical efforts.
In this large community-based study occupational exposure to asbestos and MMVF does not appear to contribute to the lung cancer burden in men in Central and Eastern Europe. In contrast, in the UK the authors found an increased risk of lung cancer following exposure to asbestos. Differences in fibre type and circumstances of exposure may explain these results.
SynopsisResults are reported from a large population study (of working people) comparing Holocaust survivors and a control group in regard to emotional distress, satisfaction in life and psychosomatic symptoms. It was found that, even 40 years after the traumatic experience, this group of survivors exhibited a slightly higher degree of emotional disorders than controls who were not under Nazi occupation during WWII. These long-term effects were usually more prominent in women than in men, and the relationship to age was minimal.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
